| patterns.

This is almost what I had in mind, although not quite. In my head, the
select patterns

  (1) para
  (2) para|blockquote|programlisting
  (3) listitem/para

would make the 'specific' table look like this:

  para -> 1,2,3 (already sorted in the right order, whatever that is)
  blockquote -> 2
  programlisting -> 2

This should shorten the 'generic' list a bit, although at some cost
during stylesheet parsing. It might help a little, though.
